The four women, who were called Headscarf Revolutionaries and lived in Hull's fishing community of Hessle Road, gathered a 10,000-signature petition calling for reform after the triple trawler tragedy.

Ms Bilocca led a delegation to Parliament and eventually met Prime Minister Harold Wilson.

A book was later written by Dr Brian Lavery telling their story.

Rights to the book have been bought by production company Red Productions with ideas of turning the story into a TV drama or film.

A ceremony was held at the Maritime Museum in the city in May last year on what would have been Ms Bilocca's 86th birthday. She died in 1988.
